Yes, the MPL and the GPL are not compatible. But you don't have to
link them together. Just use fork/exec to run gpg - this is perfectly
legal. There is also a special interface to control gpg from another
program (see tools/shmtest.c). A more convenient way would be to use
the PGG wrapper library, this is also GPLed but maybe we can
convinmce Michael to make an exception for MPL. I am very interested
to make Mozilla (or even Netscape) OpenPGP aware.
